ROAD-CART.

SPECIFICATION forming partof Letters Patent No. 352,830, dated November 16, 1886.

Application filed September 27, 1886. Serial No. 214,643. (No model.)

To aZZ whom it may concern:-

Beit known that I, ANTHONY MOAVOY, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Road-Carts, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 isaperspective view of this device. Fig. 2 is a side elevation showing one of the springs and its connection with the axleand the cross-bar. Fig. 3 is a rear elevation showing in detail the method of connecting the rear end of the side springs to the axle; Fig. 4., a front elevation showing in detail the connection of the front end of the side springs to the crossbar; Figs. 5, 7, and 8, details inside elevation of a modified form of connection between the side bar and spring; Fig. 6, a detail in side elevation of bolt between side bar and spring.

This invention belongs to that class of devices known as road-carts; and the novelty in the present instance consists in the construction of the several parts, and in their combination with .each other, whereby the requisite degree of elasticity is given to the seat, and at the same time a strong and durable carriage is obtained, all as will be now more fully explained.

Heretofore in devices of this general description, the flexibility of the seat has only been secured by a construction that was too frail for any permanent use, or else the several parts were so strong and bulkythat the requisite flexibility could not be obtained; but in my device, by the peculiar structure of the several parts and by their peculiar combination, the desired ends are secured at the least possible cost and in a very permanent manner.

The main points of novelty are the side springs and their manner of attachment at front to the cross-bar and at the rear to the axle; also the attachment of the seat-bars to the side springs; also the center connection of theseatbars with the side springs, and, finally, in the peculiar structure of theindividual parts and in their combinations.

In the accompanying drawings, A denotes the axle of the vehicle; B, the cross-bar; O O, the ends of the thills; and D D the side springs. One of these springs is on each side and below the seat,and extends from the axle to the crossbar. At the rear end each spring is secured to the bolt 6 of the clip E, which is attached to the axle A by its band 6' and the nut e. The bolt 6 passesthrough the ears 6 of the clip and is headed at one end and secured by a nut at the other in such a manner that it is free to turn in its bearings or socket to allow sufficient play for the ends of the spring. The spring thence has a downward and slightly rearward curve, and then extends forward horizontally with a slight upward curve near the middle part, and at its front end is attached to the clip F in like manner as its rear end to the clip E. This clip F is secured .to the cross-bar B by its band f and nut f at their ends, and the end of the spring D is wound over and secured to the loose bolt f which is passed through the ears f 3 of the clip, and is loose enough therein to allow a sufficiently free movement of the front ends of the spring. Each of the front ends of the seat-bars G is secured by a metal plate, 9, attached thereto and to the bolt h, which passes through the ears h of the clip H, which clip is bolted to the spring D near the front end. The seat 9 is secured on the upper rear end of the bars G. The bolt it has sufficiently free play in its ears to allow any necessary movement of the rear ends of the side bars thereon. Each of the seat-bars is also attached near its centerthat is, its mid-lengthto the side spring below it by a bolt, I. This bolt is bent at right angles at its lower end, t, and this end passes through the plate K, which plate is at its ends bolted to the top of the spring. On the end of this arm is 'a nut, t". The upper end of this bolt I passes through the plate L, which, at its ends, is bolted upon the side of the seat-bar. On its upper end is a jam-nut, i, above said plate L, and another, i below this plate. By means of these two nuts the side bars can be raised or-lowered, as may be needed to fix the position of the seat. The lower ends of these rods having free motion in theopenings in the plate K, permit free motion of the said bars on the side springs.

In Fig. 5 is shown a modification of the means of connecting the side bar to the spring. In this instance the bolt 1 is secured by means of the plate 72*, which is preferably integral with itunder the side bar at a convenient point between the seat and the lower end of the side bar, while the lower right-angled end, '5 of said bolt is passed through the plate K on the upper side of the spring D in like manner, as has been heretofore explained in reference to the bolt K.

By the structure above described I have obtained in the simplified structure a veryflexible and strong joint for the ends of the springs, the ends of the side bars, and for the central connection between the bars and springs. In this way is secured the freest and easiest motion of the seat consistent with strength and durability.

Having now described my invention, what I consider new, and desire to secure by Letters Patent, is

1. The combination of the side springs with the axle and the cross-piece and with the seatbars in the manner described, and with the bolt-connections between the seat-bar and side springs, all as and for the purposes set forth.

2. The combination of the seat and seat-bars with the side springs and the clips thereon, and with the connecting-bolts I, substantially as described.

3. The combination of the seat-bars with the side spring, the clips thereon, and with bolts and nuts whereby the height of the seat can be regulated, substantially as set forth.

4. The combination of the seat-bars with side springs, and with bolts secured to the seatbars at their upper ends and at their lower rightangled ends to the clips on the side sp ring, substantially as described.

5. The combination of the axle A and clip E, secured thereto, and the bolt e,loosely mounted in said clip, with the spring D, bent at its ends over said bolt, and thence curved under the axle and horizontally forward to the cross-bar.

6. The combination of the springs D with the plate K, bolted thereto at its ends, and the bolt I, right angled at its lower end and passing through said plate, the nut i, the seat-bars G, and the plate L, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ANTHONY MCAVOY.
